Hello all. I have a question that is a little off the usual topics. I have four of five bottles the high percentage Deet mosquito repellent, ranging from 90-100%. Most studies have concluded that percentages over 30 are pointless. What would be the best way to reduce the higher percentage Deet, down to 30-40. What additive would be best additive to use? I'm thinking isopropyl alcohol. Any opinions? Thanks to all who can offer help
